- * <p>Wraps the specified element with a special 9 element markup/CSS block that renders by default as

- * <p>This special markup is used throughout Ext when box wrapping elements ({@link Ext.Button},
- * {@link Ext.Panel} when <tt>{@link Ext.Panel#frame frame=true}</tt>, {@link Ext.Window}). The markup

- '<div class="{0}-tl"><div class="{0}-tr"><div class="{0}-tc"></div></div></div>
- <div class="{0}-ml"><div class="{0}-mr"><div class="{0}-mc"></div></div></div>
- <div class="{0}-bl"><div class="{0}-br"><div class="{0}-bc"></div></div></div>';
- * </code></pre>
- * <p>Example usage:</p>
- * <pre><code>
- // Basic box wrap
- Ext.get("foo").boxWrap();
- // You can also add a custom class and use CSS inheritance rules to customize the box look.
- // 'x-box-blue' is a built-in alternative -- look at the related CSS definitions as an example
- // for how to create a custom box wrap style.
- Ext.get("foo").boxWrap().addClass("x-box-blue");
- * </code></pre>
- * @param {String} class (optional) A base CSS class to apply to the containing wrapper element
- * (defaults to <tt>'x-box'</tt>). Note that there are a number of CSS rules that are dependent on
- * this name to make the overall effect work, so if you supply an alternate base class, make sure you
- * also supply all of the necessary rules.
- * @return {Ext.Element} The outermost wrapping element of the created box structure.
